The Coon amplitude is a \(2 \rightarrow 2\)  scattering amplitude describing an infinite number of higher spin exchanges consistent with the duality constraints [1]}, [2]}, [3]}. In particular, this mysterious amplitude is the unique solution to duality constraints having an infinity of exchanges with logarithmic trajectories. Recently, it has been brought forward as an interesting case study on its own [4]}, [5]}, [6]}, [7]}, [8]} while also serving as a useful reference to the study of accumulation point amplitudes with similar infinite towers of states [8]}, [10]}, [11]}, [12]}, [13]}.
